Hello, I am having a problem that I can't figure out. I got The Witcher 3 when it came out and played the whole game with a mouse and keyboard with no problems, zero. I stopped after I beat it and moved to other games til today when I wanted to go back and try the DLC. When I started the game my mouse acted insane. It was super slow to respond to my reactions. It would do them, only in a very floaty manner and several seconds after I moved the mouse. I could move the mouse around then stop touching the mouse and it would be a while before the cursor finished doing everything I had told it to. There was no frame drop or jerkiness to the cursor, just it was very slow to react and floaty when it started to move. Looking up the problem people suggested turning on the Enable Hardware Cursor option. I did this and was able to control my the cursor just fine. I thought the problem was fixed until I tried to click on something with the mouse. It took several seconds to click on what I told it to. I have tried reinstalling the game, checking out the mouse sensitivity function, enabling the hardware cursor as I said, nothing has worked. There is zero input lag when I move with the keyboard or click anything with the keyboard or if I try moving the cursor with the small digital mouse pad attached to my keyboard, I have the Razer SWTOR keyboard with the trackpad on the keyboard, it is just fine. I also tried using a controller and that works just fine. I prefer using the keyboard because that's what I beat the game with originally so I want to be able to use it. Also, the fact that this is happening makes me want to solve it. Does anyone know what in the world is happening?
